Dirk Hohndel ba6713f0d8 Clean up the setDive function
* This should never be called with a NULL dive.
* The dc variable was set then never used.
* We now have a unique id for each dive, but we can't simply not
  repopulate the model in setDive as the old comment might make you
  consider, as otherwise the dataModel will reference already freed data
  in pInfo.
